[lyrics][BUG] Lyrics plugin error whenever music starts playing

[HelmicNewciv]

Submission checklist

• I have searched existing issues and confirmed this is not a duplicate.
• I am using the latest available version of Noctalia and of the plugin.
• This is a bug in a community plugin, not in Noctalia itself (those belong in the noctalia repo).

Plugin

lyrics

Plugin version

1.5.0

Bug description

Noctalia reports the Lyrics plugin has stopped responding and was disabled whenever music in a supported player starts to play. I have never been able to get it - or any other lyrics plugin like LRC - to actually display lyrics, but this is the only plugin that shows an error.

Steps to reproduce

1. Install and enable Lyrics plugin. It is not necessary to add the widget to the panel, though this happens with the widget as well
2. Open a media player in Lyrics's allowed players list or that is otherwise supported.
3. Play music.

Expected behavior

Lyrics should display in the widget.

Actual behavior

Noctalia sends a notification stating that the plugin has become unresponsive and that it has been disabled.

Environment information

Additional context

None of the lyrics plugins seem to work, but they do not show any error messages. If I use something like lrc_tty in the terminal, it can display lyrics just fine, but none of the plugin widgets will display anything, nor do the plugins show any error messages in nocatlia.log.

Fixed in #604 by updating Lyrics to 1.5.1 and avoiding unnecessary xesam:asText polling unless MPRIS lyrics are enabled.

It appears the same error keeps showing after updating to 1.5.1. Did a full system update and two reboots, still same error, still the same conditions.

更新到 1.5.1 版本后，似乎仍然出现同样的错误。我进行了完整的系统更新并重启了两次，但错误依旧，情况仍然一样。

Try turning off (closing/crossing out) Musixmatch and mpris in the Automatic Fallback section of the etymology settings, and try again.

尝试在词源设置的自动回退部分中关闭（关闭/划掉）Musixmatch 和 mpris，然后重试。

Same error, same line, 813. Lyrics was on 1.5.2. Did not see mpris in Automatic Fallback at all. Tried every lyrics source other than Automatic Fallback as well to test, same error.

Test out version 1.5.3.
?🤔?

[luau] plugin h465855hgg/lyrics:service: call to 'async command callback' failed: [string "/home/helmic/.local/state/noctalia/plugins/materialized/community/lyrics/lyrics_service.luau"]:832: script callback 'async command callback' exceeded its CPU budget

Notably this no longer happens with every song, and on some songs it seems to actually work or at least does not exceed the CPU budget when it fails to fetch lyrics. It'll work with songs that I've provided LRC files in the same folder, but it'll also fail with other songs I've provided LRC files in the same folder. It'll work with some songs that I have not provided an LRC file for, but then fail for others.

I don't know if that behavior makes sense to you or not. I don't believe this was the behavior with previous versions, but I could spend time testing older versions if you wish to see if the change you just made was actually responsible or if I missed something in my testing.
